A secondary analysis of data collected in Wave 4 of Footprints in Time, Australia's Longitudinal Study of Indigenous Children, was conducted to help address this research gap. The study results ind...
Male reproductive performance has more impact on overall herd productivity than in the female. In order to assess herd productivity in cattle in Nyagatare, Eastern Rwanda, the proportional distribution of male reproductive organ abnormalities was investigated in 3087 bulls slaughtered over a 4-year period. The aim of the study was to investigate the proportional distribution of male reproductiv...
Seventy-five turtles Podocnemis expansa in the Brazilian Amazon were examined for the presence of ectoparasites and hemoparasites. Samplings were performed in three study areas in the state of Tocantins, Brazil. Twenty-five specimens were sampled per study area (a commercial breeding facility, an indigenous subsistence breeding facility and a wild population of the Javaés River). Hemoparasites ...

Five strains of adult mice were immunosuppressed with the synthetic glucocorticosteroid dexamethasone (DEX), administered either orally or intraperitoneally. The strains of mice used were C57BL/6N, DBA/2N, CBA, C3H/HeN, and BALB/cAnN. All mice were evaluated for susceptibility to Cryptosporidium parvum after intragastric inoculation with 10(6) oocysts per mouse. The DBA/2N, CBA, C3H/HeN, and BA...
Basic physiology, hematology and serum chemistry of indigenous chicken, reared in eco-friendly environment of backyard of small farmers in temperate regions of J and K State (altitude range 1500-2000 m amsl, average temperature 13°C), was studied in adult chicken from different pockets of Kashmir. The average values for haemoglobin (Hb), Packed Cell Volume (PCV), Total Leukocyte Count (TLC), To...
Data from ten sources comprising 3,851 flocks were modelled to identify variation in levels of mortality in laying hens. The predicted increase with age was curvilinear with significant variation between the seven breed categories. Mortality was higher in loose housing systems than in cages and variable within system, confirming previous reports. Cumulative mortality (CM) was higher in flocks w...

The evaluation was based on the determined levels of bacterial concentrations and qualitative identification of isolated microorganisms. MATERIALS AND METHODS The study covered 5 poultry houses: two hatcheries and three hen houses with the litter bed system. The air was sampled in three ...
